Looks like burning some diamonds to me We have done that carbon pillar experiment several times. You can add some bicarb to the carbon to get rid of the acid after that wash, filter and dry it compleatly Mill or grind the powder and wash it with hydrochloric or dilute nitric acid, sulfuric isn't the best choice We have done that few times and the product looks uniform like carbon, but we don't have an idea how to test the purity
There's actually an allotrope of carbon that is (in theory) harder than diamond. Lonsdaleite, a form of shocked carbon that gets formed when a graphitic meteor impacts the Earth. Most samples contain too many impurities to attain its theoretical hardness, but calculations say it should be half again as hard as diamond.
boron nitride is one of two materials that we have discovered that harder than a diamond, by a factor of .17 i believe. The other is like .60, which is crazy, but i don't remember what it is
An interesting experiment involving carbon nanotubes, if you can get hold of them or synthesise them: the surface of the C nanotubes can be oxidised by HNO3 to give carboxylic acid (COOH) functionalites, which can then be reacted with amines to form amide (CONH2) linkages: C nanotubes with polypeptides bonded to the surface.
I think the most interesting part of the magnesium/dry ice reaction is that the dry ice is still cold afterward. Anything else would be too hot to touch lol
To remove the MgO from the dey ice thermite run, maybe try a fusion in molten sodium bisulfate? This is very acidic, and can be driven to very high temperatures(over 250C). This extreme heat plus high acidity should totally break down the magnesium oxide byproduct. In addition, bisulfate is non-oxidizing, so it shouldnt harm the carbon produced.
Is it possible that the magnesium sulfate isn't very soluble in high concentration sulfuric acid? I.e you need more water to dissolve the salt so that the acid can act on the magnesium?
What would happen if you put hydrogen gas from water electrolysis into a container of carbon? I have been wanting to try that but im not sure what will happen.
I agree with your diamond comments and I'd like to add that with natural ones there is the whole "conflict minerals" side, where lots and lots of people get their hands cut off, shot, raped, etc. Which is not really the sentiment most people intend with gifts of jewelry.
Lovely work. The thing is that most applications do not require very pure carbon. Which is just as well since charcoal can absorb (or adsorb) just about anything. I thought that you were going to make some graphene using sticky tape at the start. I have heard that it is pretty simple but never seen it done.
Elyjah Vasquez Adsorb refers to chemical bonding on a substrate. Both adsorption and absorption are involved if activated charcoal is used as a filter material.

Can silicon, germanium, tin, or lead form diamonds too?

13:20 that's when tomuch sugar meets my stomach acid and then I have to go use the bathroom.

Boron nitride makes a super hard coating for metal cutting bits and end-mills!
my favourite part about it is that it contains boron, because one doesn't see a whole lot of boron around
The other one is Isandelite
Carbon is fascinating. Great video, thanks.

Excellent video. Thanks!
What is carbon's pure elemental form?
Super interesting as always!

That's a very good point. I've run into that problem before!

Matt I think a hydrocarbon would form, but you might need a bit of heat

j_sum1 adsorb?

j_sum1 himself, outside science madness, I don't believe it
rt tr Aww, I'm not THAT famous
Yeah I've heard about the tape thing too; honestly forgot about it for the video. I'm not sure how I would show that it actually is graphene, though.
So what's your favorite form of carbon?
Hm, probably graphite just because it has so many uses for me!
19:20 y dun u also look at the bottom of the other dry ice 2 c whats there??
I did; it was just some more scorch marks!
mrhomescientist i mean u should show us about them even its trivial stuff since its also part of the results
Just in time for my bed time, thanks :D
try pyrolysis process of sugar
Nice vid thanks for the education 👍
No carbón at the end? We want grafene!
Me South Africa 🇿🇦
Diamonds are not the hardest. Graphene
Finally made it here 1st!
Lucas Wang nope
Second ! :D
